I've been rebuilding my 951 engine. So far it's been going really well. I found a block that's within specs and looks great (also been hot tanked). The head and valves looked really good. I've got a full rebuild kit so I can do a proper rebuild.*
I've been using a product called purple power to clean and degrease many parts. I'm sure many of you have used it. It's been working really well...until tonight.*
Good turbo block (I was told it had 57K on it):

All is well so far right?? Well now onto my cam housing. I let it soak in a Purple Power solution (about 4 parts water and 1 part PP):*

On the right is what soaked in the PP mix. Look what it did to the machined surface!! Not only is the mating surface irregular, but the cam follower journal is too! The followers don't seat the same either. There's a bit more play in them.*
I can't believe what happened! Oddly enough, the plastic container I used shows no damage. So beware fellow enthusiasts!*

It soaked overnight.. Too long I guess. I never thought it would eat through metal, especially with a good amount of water mixed in. Live and learn I guess!
Much like the clutch story huh??

Read a few stories on the net about "Do not soak". Lart or Josh B should be able to fix you up with a Cam Tower. I guess you can be grateful you did not soak the block

I used it to clean the carbon off the tops of my pistons on the engine Im building, I NEVER let it sit over night !!! I was scared it would do that!!! I figured out that if you let it soak for an hour and scrub the heavy stuff off then let it soak again and keep doing that it works great!!!! the bad thing it that stuff is VERY bad for your skin!!! So gloves and eye protection are a must..... That stuff work great on EVERYTHING!!!! Cleans my concrete garage floor great, but it looks weird with all the clean spots now....hahaha

Ive never had that issue but ive never soaked something in it for very long.
Using hot water works better than soaking, FYI. A spray bottle also helps it work a lot better, I use a $20 plastic garden sprayer. That combined with hot water gets anything off/out/clean/etc.

I use purple power to clean all my parts, a-arms, oil pans, headers, but I use it leave for 3-45 sec and rinse off, is a acid read the instructions, best degreaser ever
good news is that I have all the parts that you damaged available

Out of curiosity, where/when did you get that block?

Yea, the only problem I've had with it (actually the sister product Superclean) is that it works too well and removes that invisible thin coat of oil that is on places like the cam cover, ATV engine, transcase, etc. They then start to slowly corrode with little spots showing up a few months later. There's probably something better but my fix so far to mist on a little thin oil after everything is rinsed and dry.
Will have to try it on the floor, good idea.

PS. it goes after magnesium even worse than aluminum.
PSS. I put some in my parts cleaner but the fumes are too strong to stand near it.
